Stanley, ID to Buffalo, WY: Road Trip Guide & Hidden Gems

At 6,850 feet, Teton Pass is the highest point on this drive, crossing the Wyoming border near the end of the journey. This historic mountain pass has been used by travelers since the 19th century, offering a dramatic final ascent before descending into Jackson Hole.

The route covers approximately 290 miles, taking you from the Sawtooth Mountains through high desert plains and over the Continental Divide. Plan for 6 to 7 hours of driving time without stops.

Route Overview

Road quality is generally good, but watch for wildlife, especially deer and elk at dawn and dusk. Carry chains in winter, and allow extra time for Teton Pass. The route is family-friendly: Craters of the Moon offers easy walks and a visitor center; Jackson has a town square with a kids' playground; and Yellowstone's south entrance is just 60 miles from Jackson if you have time.

For pets, most rest areas have designated pet-walking areas, and many hotels in Idaho Falls and Buffalo are pet-friendly. Carry water and a bowl for your dog, as summer temperatures can reach 90°F in the desert sections.

To manage fatigue, plan stops every 2 hours. Notable rest areas: the Galena Summit overlook (elevation 8,701 feet), the Idaho Falls Riverwalk, and the Gros Ventre River pullout near Kelly, WY. For a meal, the Snake River Brewing in Jackson offers local craft beer and pub food; in Idaho Falls, the Blue Grill is a reliable choice.

Hidden off-route spots: just south of Arco, the EBR-1 nuclear reactor (first to generate electricity) is a fascinating detour; and near Dubois, WY, the National Bighorn Sheep Interpretive Center offers unique wildlife viewing. These are slightly off the main path but highly rewarding.

Fuel stations are sparse between Stanley and Idaho Falls, so fill up in Stanley or at the small town of Challis (48 miles southeast). After leaving Idaho Falls, you'll find regular services along Highway 26 until Jackson. In Wyoming, gas stations are limited on Highway 191 until Buffalo.

• Driving time: 6.5 hours (with short breaks)
• Best time to travel: June through September for clear roads
• Road conditions: U.S. 20/26 out of Stanley is narrow but paved; later stretches are broad highways
• Seasonal closures: Teton Pass can close briefly during winter storms

There are no toll roads on this route. Cell service is patchy, especially in the Sawtooth National Recreation Area and along the Teton Pass, so download offline maps. The speed limit on highways is typically 65-70 mph, but reduce to 35 mph on the pass.

Heading east from Stanley, you'll parallel the Salmon River through the Sawtooth National Recreation Area, with the massive Sawtooth Mountains to your south. After Galena Summit (8,701 feet), the landscape transitions to sagebrush steppe, reaching the lava fields of Craters of the Moon National Monument near Arco. This volcanic terrain is a geological wonder, featuring cinder cones and lava tubes.

In Idaho Falls, the Snake River Greenbelt offers a pleasant break. Further east, you enter Wyoming via Teton Pass, descending into Jackson Hole with the Teton Range in view. The route passes within 20 miles of Grand Teton National Park, but the drive itself is scenic enough.

Local commerce is most notable in Idaho Falls and Jackson, where you'll find Western-themed shops, art galleries, and restaurants. In Stanley, a small mountain town, you can grab supplies at the Stanley Mercantile. Between towns, look for roadside fruit stands near Rexburg selling huckleberries in season.

Idaho Falls is home to the Museum of Idaho, and Jackson offers the National Museum of Wildlife Art. These are good options if you want to stretch your legs and learn about the region.
